Hydrothermal Vents – Vicki Billings

Vicki Billings gave a very interesting & informative talk on these sub-oceanic phenomena associated with hydrothermal vents. She covered the physics, geology, and ocean chemistry associated with their formation, and exotic life forms dependent on chemo- (rather than photo-) synthesis enabled by them; also the deposition of mineral deposits on the ocean floor and on land in ophiolite rocks near obduction zones.
